This is my first question so sorry if its a poor one for this style of forum.
I regularly write and sight-read standard notation but there are plenty of times im caught without pen and paper or a computer. When that happens I usually just record the idea on my phone using my voice if at all possible. However, if im on a plane, for example, that's not practical. So my question is:
Is there any good android applications that allow you to write your own sheet music?...Preferably with audio playback.
